It remains after use has ended a predetermined period of time switched on. Similar devices are also from JP-A-2001262663, JP-A-09195359, JP-A-07279213 and JP-A-07268928 are known.
  • the invention has for its object a device and a method of avoiding annoying odors on toilets too create, on the one hand, smells very effectively and reliably can be suppressed and on the other hand the production excess ozone is avoided.
  • this task is solved by using the sensor the extracted air is examined for oxidizable odor molecules and generates a signal that makes the concentration more oxidizable Reproduces odor molecules in the extracted air, the Ionization device depending on the signal of the Sensor is controlled.
  • the Fan controlled by the sensor signal e.g. in the way that the fan with an initial, relatively low power works when the control signal has no oxidizable odor molecules indicates, and that he has a second, higher power works when the control signal the presence of oxidizable Indicates odor molecules in the extracted air.
  • the fan preferably works in the standby state, i.e. if the sensor does not detect any odor molecules, for example at half power while it is when the sensor is present of odor molecules detects full performance is switched. Simultaneously with the start-up of the fan the ionization device is activated. The deodorization device catches practically without delay working on. Another advantage is that the deodorization device is only activated when it is actually necessary is.
  • the deodorization module the control is designed so that that at certain intervals, e.g. every 24 hours, one Reset is carried out.
  • the sensor can move in the direction of the air flow generated by the fan in front of, behind or next to the ionization device be arranged. It is only important that the sensor is inside of the air flow generated by the fan is arranged before this airflow exits into the room again. If the sensor is arranged behind the ionization device, so at the determination of the control curve to take into account that some of the oxidizable odor molecules have already oxidized is before they could reach the sensor. The dependence the power of the ionizer from the sensor signal then has at least in part the character of a regulation.
  • the sensor has a triple function: Firstly, the ionization device is switched on as soon as the sensor detects oxidizable odor molecules, secondly the sensor controls the performance of the ionization device as a function of the concentration of the detected odor molecules, and thirdly the performance of the fan is increased as soon as the sensor detects oxidizable odor molecules.

  • hydrogen has the advantage that it is not used in perfumes and similar cosmetics, so that a false response of the sensor to such cosmetics is prevented.
  • H 2 sensor thus has the advantage that on the one hand it responds reliably if there are any odor molecules or air components that result from human digestion, and on the other hand an incorrect response to e.g. B. cosmetics is avoided.
  • Suitable H 2 sensors are also available from Fis Inc. (see Products Review, Sensors and Systems Technology, revised June, 1998, version 4.2 from Vis Inc.), e.g. B. the model SB 19.

  • the float 82 is built inhomogeneously inside, so its focus is close to the cut surface from the purge flow is turned away. At rest, i.e. when there is no water in the Is located, the float therefore takes the one in FIG.
  • FIG 21 shows a torsion valve 84.
  • the torsion valve has a rectangular frame 86, which in the flushing pipe 42nd is used and annular at the front and rear end Has supports 88.
  • a two-part float 90 is in the frame 86 rotatably supported, the axis of rotation with the Longitudinal axis of the flushing pipe 42 coincides.
  • the two parts of the float are half cylinders and in terms of Flushing flow downstream half cylinder is a to Axis of rotation coaxial channel 92 is provided.
  • a flexible rubber tube 94 connected with a Angle piece 96 is connected, which in turn upwards from the Flushing pipe 42 is led out and connected to the suction pipe 22 becomes.
  • the two parts of the float 90 are so far put that rubber tube 94 between them still can be brought out.
  • the Float 90 mounted so that an axial opening 98 free remains. Through this opening 98, the channel 92, the rubber tube 94th and the angle piece 96 is thus a free channel that continues in the intake pipe 22. If there is no in the flushing pipe 42 There is water, so the float 90 turns through Weight down. The rubber tube 94 is inserted so that then it is wrinkle-free. The float turns when rinsing 90 due to its buoyancy by 180 ° upwards. The rubber tube 94 is twisted so that it blocks the passage and then no more air is sucked through the intake pipe 22 can.
  • the upstream part of the float 90 has a helical shape Grooves or webs on its semi-cylindrical Surface, which determines the direction of rotation in the the float 90 rotates upward about its longitudinal axis.
  • the Plug connection between the two parts of the float 90 is designed so that this rotation is not hindered, i.e. the connector elements are on the quarter circle limited, which initially turns down when rotating rotates.
  • two semicircular ones can also be used Apertures can be rotated against each other.
  • the opening 98 be semicircular and the channel 92 or at least Also be semicircular at the beginning.
  • the semicircular Openings are arranged so that they are aligned when the float 90 is in its lower position, so that there is a free connection. The swimmer is in its top layer, the semicircular openings are around Twisted 180 ° against each other so that the connection is blocked is.
